If you ever have the [Next >] button disappear off your dashboard again, there’s an easy trick to get to the next page anyway. Go to the last post on the page and open a reblog of it in a new tab. In the address bar, the URL will have a long number; copy that number, then paste it in place of the long number in the URL of the page with the missing [Next >] button and advance the page number by one, then refresh the page. It will take you to the next page, and bring back the [Next >] button. -texasuberalles
